fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

* mark struct vm_area_struct::vm_ops as const
* mark vm_ops in AGP code
But leave TTM code alone, something is fishy there with global vm_ops
being used.

Previously, the only external (to dispc.c) IRQ handler was RFBI's frame
done handler. dispc's IRQ framework was very dumb: you could only have
one handler, and the semantics of {request,free}_irq were odd, to say the
least.
The new framework allows multiple consumers to register arbitrary IRQ
masks.

Leaving interface clocks enabled causes dss pwrdm to stay in active state
when mpu is in active state. This fix puts dss to sleep state when it is
not needed.
Earlier version broke framebuffer on 24xx. This is fixed by enabling
clocks before trying to access DISPC_IRQSTATUS register.

The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270
degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD
Panel Configuration Register). Now it is possible to use this caps only
setting the angle degree on var rotate of fb_var_screeninfo using the
FBIOPUT_VSCREENINFO ioctl.

Add glue to control the OMAP_LDP LCD as a frame buffer device using the
existing dispc.c driver under omapfb.
Patch updated for mainline kernel. Note that the drivers/video/omap
should be updated to pass omap_lcd_config in platform_data. The patch
should also be updated to compile if twl4030 is not selected, and
eventually to use the regulator framework.

The 3430SDP uses the same panel as the 2430SDP. The main difference are
in the GPIO lines used for panel enable and backlight, and the VAUX
register/commands sent to the TWL4030 power subsystem.
Also, some misc. whitespace cleanups.

This is an updated version of the LCD driver for the Amstrad Delta to take
into account the recent changes to the omapfb infrastructure. The Delta
features a 480x320 12 bit DSTN panel.

Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS,
and convert omap_read/write into a functions instead of a macros.
Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE.
In the long run, most code should use ioremap + __raw_read/write instead.
